JOSEPH R. BROWN, OF PROVIDENCE, RHODE ISLAND.

AUTOMATIC FIRE-EXTINGUISHER.

SPECIFICATION forming part of Letters Patent No. 257,549, dated May 9,1882.

Application filed November 11, 1881.

To all whom it may concern Be it known that I, JOSEPH R. BROWN, of thecity and county of Providence, and State of Rhode Island, have inventeda new and useful Improvement in Automatic Fire-Extinguishers and Ihereby declare that the following is a full, clear, and exactdescription of the same, reference beinghad to the accompanyingdrawings, forming a part of this specification.

The invention has reference to an improvement in distributers for water,arranged to open automatically; and it consists, first, in a deflector,perforated or not, which is secured by a metal fusible at a lowtemperature, and which, when released, will spread the water issuingfrom the outlet.

It further consists in providing such a deflector with a stem,on theupper end of which is a valve or plug, by which the outlet is closed andthe water is prevented from reaching the soldered joint.

Figure 1 is a view of one form of my improved automaticfire-extinguisher. Fig. 2 is a sectional view of the same, showing theposition of the distributer. Fig. 3 is a sectional view of a distributerprovided with a non-perforated deflector.

In the drawings, A is a piece of pipe, provided with the valve-seat b atits upper end, into which, or against which, the valve 0 is held by thestem d, the lower end of which is providedwith a screw-thread and theextreme end slotted,sothat it can be turned in the nut formed in thedistributer E. A 1ock-nut,f, may be used to firmly hold the stem. Thestem at is held in the center of the pipe A by the guides shown in thedrawings, and near the outlet end of the pipe A a surface, 9, is formedon the pipe, to which the distributer or deflector is secured by asolder fusible at a low temperature.

The valve 0 may be in part formed of a material fulsible at a lowtemperature, so that this valve itself will melt before a fire can getmuch headway, if by any means the fusion or melting of the solder bywhich the distributer is secured to the pipe should fail to release thevalve. Such an emergency may arise, though (No model.)

not at present apprehended. The melting of the valve 0, or part of thesame, will allow the water to flow to the distributer E, and when thesame is perforated, as shown in Fig. 2, will be discharged on the. fire.

The device, as shown, is secured and made ready for attachment in theshop, the valve 0 closing the inlet, and when attached to the usualpipe-fittings in a building it is to be pendent from the pipes. As thewater cannot pass the valve 0, the soldered joint 9! is not affectedby-the same, and will melt, or at least fuse enough to release thedistributer from the pipe, and, as the full pressure is acting on thevalve, the distributer will be projected downward and held suspendedbelow the outlet by the valve resting on one of the guides, as is shownin Fig. 2. The water willbe discharged downward and sidewise through theholes in the distributer, as shown in Fig. 2 5 or it will be thrownagainst the ceiling and spread in every direction, if the unperforatedconical deflector is used, as shown in Fig. 3.

This automatic fire -eXtinguisher is much more prompt in its action thanthose in which the water can come in contact with the fusible solder orwith the metal to which the seal is secured by fusible solder, as inthis extinguisher the solder is removed a considerable distance from thewater.

The pipes conveying water to the distributers can be secured close tothe ceiling and the distributer be screwed into the fittings so as to besuspended below the pipes. The ceiling will thereby be perfectly coveredwith water and assist the distribution of the same.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In an automatic fire-extinguisher, the combination,with the pipe A, provided with a contracted outlet and an annularsoldering-surface, of the valve 0, constructed to exclude-the water fromthe distributer, and a conical distributer secured by solder, asdescribed.
